PHASE1
Brief Summary
AlphaMedix™ (²¹²Pb-DOTAMTATE) is a radiotherapeutic drug indicated in subjects with unresectable, metastatic somatostatin receptor (SSTR) positive neuroendocrine tumors (NETs). Because 212Pb is an in ...
Detailed Description
This dose escalation study will include a maximum of 50 subjects with histologically confirmed NET, a positive somatostatin analogue scan, and no prior history of PRRT therapy. The study will begin w...
Eligibility Criteria
Inclusion
- ECOG status 0-2.
- Life expectancy of at least 12 weeks.
- Histologically confirmed diagnosis of SSTR (+) NET, unresectable or metastatic.
- Measurable disease per RECIST 1.1 on CT/MRI scans, defined as at least 1 lesion with ≥ 1 cm in longest diameter (LD) (lymph nodes along short axis).
- Appropriate diagnostic imaging studies, at the discretion of the PI including but not limited to CT, MRI, 18F-FDG PET/CT, NAF PET/CT bone scan, ultrasound, etc. of the tumor region or suspected area within the 4 weeks of dosing day.
- SSTR(+) disease, as evidenced by available FDA approved SSTR imaging (SRI) within 4 weeks prior to the first cycle.
- All FDA-approved therapies for which the subject is eligible have been exhausted.
- Recent blood test results (within 2 weeks pre-dose) as follows: Sufficient bone marrow capacity as defined by white blood cell (WBC) ≥2,500/µl and WBC ≥2,000/µl for subsequent cycles; platelets ≥ 100,000/µl for the first treatment and ≥75,000 for the subsequent therapies, hemoglobin (HgB) ≥8.9 g/dl for the first treatment and 8.0 g/dl for the subsequent therapies, ANC ≥1,500/µl for the first treatment and ≥1,000/µl; for the subsequent therapies; ALT, AST values ≤3 times upper limit of normal (ULN); Bilirubin: ≤3 times ULN; Serum creatinine ≤150 µmol/liter or 1.7 mg/dl; Negative pregnancy test in women capable of child-bearing within 48 hours of administration; Serum albumin \> 3.0 g/L (\<3.0 g/L may be acceptable at the discretion of PI, if PT, PTT, and INR are within normal range)
Exclusion
- Prior whole-body radiotherapy and PRRT using 177Lu/90Y/111In- DOTATATE/DOTATOC or TAT
- Known hypersensitivity to 68Gallium, Octreotate, or any of the excipients of 68Ga-DOTATATE, AA infusion or AlphaMedix™.
- Therapeutic use of any somatostatin analogue, including Sandostatin® LAR (within 28 days) and Sandostatin® (within 1 day) prior to administration of investigational drug.
- Subjects with unusual hematological parameters, including an increased mean corpuscular volume (MCV) (\>100,000), and especially in those who had previous chemotherapy, the advice of a hematologist should be sought for adequate further work-up to rule out myelodysplastic syndrome (MDS).
- Any subject who is taking concomitant medications that decrease renal function (such as aminoglycoside antibiotics).
- Female subjects who are pregnant, lactating or women of childbearing potential not willing to practice effective contraceptive techniques during the study period and for 8 weeks post-injection or male subjects who have female partners of childbearing potential not willing to practice abstinence or effective contraception, during the study period and for 8 weeks post-injection.
- Current somatic or psychiatric disease/condition that may interfere with the objectives and assessments of the study.
- Indication for surgical lesion removal with curative potential
- Known brain metastases; unless these metastases have been treated and stabilized 6 months prior to enrollment
- Completion of: (1) cytotoxic chemotherapy for less than 6 weeks; (2) a biological agent for less than 5 half-lives; and (3) radiation therapy for less than 6 weeks prior to study enrolment,
- Uncontrolled congestive heart failure; subjects suspected of having this condition need to show ejection fraction of \>55% as determined by multigated acquisition (MUGA) scan.
- Carcinoid heart disease: Prior history of torsade de pointe, or congenital long QT syndrome; Conditions with screening ECG repolarization difficult to interpret, or showing significant abnormalities. This includes, but is not limited to: high degree AV block, pacemaker, atrial fibrillation or flutter; QTcF interval \> 480 msec on screening ECG; Significant hypokalemia at screening (Potassium \<3.5 mMol/L); Significant hypomagnesemia at screening (Mg++ \<0.7 mMol/L)
- GFR \< 35 mL/min
